DEPOT is a framework for easily storing and serving files in web applications on Python2.6+ and Python3.2+.

Installing DEPOT can be done from PyPi itself by installing the filedepot distribution:

$ pip install filedepot

To start using Depot refer to Documentation

DEPOT was presented at PyConUK and PyConFR in 2014

Here is a simple example of using depot standalone to store files on MongoDB:

from depot.manager import DepotManager

# Configure a *default* depot to store files on MongoDB GridFS
DepotManager.configure('default', {
    'depot.backend': 'depot.io.gridfs.GridFSStorage',
    'depot.mongouri': 'mongodb://localhost/db'
})

depot = DepotManager.get()

# Save the file and get the fileid
fileid = depot.create(open('/tmp/file.png'))

# Get the file back
stored_file = depot.get(fileid)
print stored_file.filename
print stored_file.content_type

• MemoryFileStorage provides in memory storage for files. This is meant to provide a convenient way to speed up test suites and avoid fixture clean up issues.
• S3Storage can now generate public urls for private files (expire in 1 year)
• Files created from plain bytes are now named "unnamed" instead of missing a filename.

• S3Storage now supports the prefix option to store files in a subpath

• Storages now provide a list method to list files available on the store (This is not meant to be used to retrieve files uploaded by depot as it lists all the files).
• DepotExtension for Ming is now properly documented

• It is now possible to use multiple WithThumbnailFilter to generate multiple thumbnails with different resolutions.
• Better documentation for MongoDB UploadedFileProperty 

• Fixed a bug with Ming support when acessing UploadedFileProperty as a class property
• Improved support for DEPOT inside TurboGears admin when using MongoDB

• Added DepotManager.alias to configure aliases to storage. This allows easy migration from one storage to another by switching where the alias points.
• Now UploadedFileField permits to specify upload_storage to link a Model Column to a specific storage.
• Added policy and encrypt_key options to S3Storage to upload private and encrypted files.

• Added host option to S3Storage to allow using providers different from AWS.

• Added FileIntent to explicitly provide content_type and filename to uploaded content.

• Added Content-Disposition header with original filename in WSGI middleware

• Work-Around for issue with wsgi.file_wrapper provided by Waitress WSGI Server

• Official Support for AWS S3 on Python3
